SPECIFICATION forming part of Letters Patent No. 691,292, dated January 14, 1902.

Application filed March 28, 1901. Serial No- 53,205. (No model.)

To (Z5 whom it may concern:

Be it known that I, EDWARD'SANDsTRoM, a citizen of the United States of America; and a resident of Wilmington, county of Newcastle, State of Delaware, have invented certain new and useful Improvements in Beet and other Root Digging Machines, ofwhich the following is a specification.

My invention consists, essentially, of two series of radiating spoon-shaped spades set edge to edge in circles and fronting each other in a wheeled carrier, which beingdrawn along the ground forces the spades into the ground on the sides of the rows of beetsoiother roots, respectively, and by means of suitable cams causes the spades to close on and grip the beets after entering the ground beside them and raise them in the ascen'dingcourse of the spade alongyvith more or less earth to the uppermost range of the spades,where they open and drop the beets into ascreen,whereby the accompanying earth is separated and from which the beets are discharged into car riers and therebydelivered into a' receptacle in which they are collected in quantities to be discharged in piles from time to time, as hereinafter more particularly described, reference being made to the accompanying drawings, in which- 0 Figure 1 isaplan view of myimpr'oved beet-' digging machine with some parts in horizontal section. Fig. 2 is a longitudinal sectional elevation on line 2 2 of Fig. 1. Fig. 3 is'a central vertical transverse section. Fig. 4 is 5 a rear elevation, and Fig. 5 is a central longitudinal sectional elevation with a rear partof the machine broken off.

In the first place there is a horizontal frame comprising side members (1, preferably in 40 two parts with an intermediate space, one

hind transverse member b, and a front transverse and intermediately offset member 0, which frame carries at the middle of each side member an upright grooved post 6, and the posts and the said side members a have an outwardly-extended short axle cl, by which said frame is mounted in a pair of carryingwheels f. The upper ends of the posts care coupled by a truss g for stability.

In the groove'of each post e is a verticallyshifting journal-box h, in which a shaft 2',

boxes, is mounted.

which extends from one to the other of the This shaft carries near its center two series of spoon-shaped spades j, with their cutting edges pointing outward radially and set edgewise to each other in transverse planes of the shaft by means of rings 75, supported on suitable arms Zof hubs m of said shaft, the spades of each series being set fronting spades of the other series in radial lines of the axes, and they are pivoted by short arms 11. to the supporting-rings 7c, so as to swing toward and from eachother in longitudinal planes of the shaft. The shaft is normally carried at the lowest posiiion' of its boxes h in the grooved posts, whereby'it will be seen in Fig. 3 that the spades penetrate the ground through the effect of the'weight on them, so as to be rotatedas the machine is drawn along on the These two-series of spades cam-ring 0 behind each series ofspades, which causes the spades to close on the beets after being thrust in the ground beside them and grip and raise them out and carry them to the upper range of the course, where said cams diverge at r and permit the beets and the accompanying earth to fall out of the spades. 'Springsp are employed to insure the opening of the spades in case the earth should pack and the spades should stick.

The spoon-bowl form of the spades is considerably less complete on the edge that approachesthe beets when entering the ground than on the other edge for free entry of the (See 46 on some of the spades.) On the other edge the bowl shape is entire for the more effective closing of the spade edges behind the beets for more certainty in lifting the beets out of the ground.

In Fig. 1 it will be seen that the cams allow wide opening of the spades entering the 5 ground; but when entered the cams close the spades to the extent shown in Fig. 3 and maintain them about the same until reaching the uppermost position or thereabout, where the notches 0' allow the spades to open with [03 -a sudden shock, designed to shock the earth No. 69|,293.'

APPARATUS FOR DISPENSING BEVERAGES.

SPECIFICATION forming part of Letters Patent No. 691,293, dated January 14, 1902.

Application filed February 20, 1901. Serial No. 48,105. (NomodeL) To all whom, it may. concern:

Be itknown that LHERMAN SOHEPKE,a citizen of the United States, residing at Chicago,-

in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus forDispensing Beverages and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in air on the liquid in the container, doublechanneled pipe or tubing for conveying the air to the container from the faucet and the liquid from the container to the faucet, a bung having channels for the air and gas, and various liquid and air tight couplings for joining the several parts, all uniting to form a complete and compact form of liquid-distribution apparatus.

In this application I will describe and illus tratemyinventionas apparatusfordispensing beer,though I do not thereby wish to be understood as limiting it to such uses. In the systems of beer distribution in general use an outfit comprises an air pump and tank,an air-pressure gage,and an air-pressure regulator,interposed between the air-tank and the keg of beer. Faucets are connected with the kegs by pipes leading through an ice-box, whereby the beer is cooled before being drawn,and separate pipes connect the air-gage,regulator, and tank with the kegs. The gages are usually placed at inconvenient points, and the air conveying pipes are exposed to the atmosphere -of the saloon or cellar, so that the air when pumped over the beer is more or less warm. The multiplicity of pipes and parts makes the material and installation-of such systems expensive and troublesome and causes the cutting of numerous openings in the floors and partitions.

The chief object of my invention is to improve and simplify the parts and reduce their number and to arrange them conveniently for use and ready access when repairs are needed.

In the accompanying drawings, which form a partof this application, Figure 1 shows in elevation my improved liquid-dispensing apparatus as installed for use in drawing beer. Fig. 2 is a view in front elevation of the faucet forming a part of my invention and its airpipe connections. Fig.3 is 'a longitudinal section through the said faucet and an elbow connection therefor. Fig. 4 is a vertical section through the bung and its connections, also forming a part of my improved apparatus. Fig. 5 isa detail showing a cross-section through the bung attachment on the line was of Fig. 4. Fig. 6 is a detail showing a crosssection of the double-channeled beer and air conveying pipe.

' Referring to the drawings in detail, A represents the faucet feature of myimproved apparatus, thesame being placed back of the bar.

E represents the bung element of the apparatus, which is attached to the keg as shown in Fig. 1, and G is the double-channeled pipe connecting the bung with the faucet and serving as a conduit for the air and the beer. F

The faucet A comprises a tubular portion ct, through which extend a beer-channel and an air-channel, which are entirely separated by a longitudinal partition a At the forward end of the faucet and forming a part thereof is an air-pressure gage B, of wellknown form, comprising an expanding spring b, a dial b and a hand b the air being admitted to said gage from an air-chamber b in the faucet through an opening b in the back of the gage.

struction than that shown may be used, the attachment to the body of the faucet being made in any suitable manner. Above the air-chamber b and screwed into a circular threaded opening in the tubular portion a is a dome D, in which is housed the air-admission-regulating device hereinafter described.-

The specific form of the air-gage is immaterial, and any other con- Said dome is composed of a collar d, threaded at its lower edge to screw into the opening a of a cover 01 screwed into the upper portion of the collar, and a hollow cap 61 screwed into the central threaded opening in the cover. A suitable opening through the side of the collar admits an air-inlet pipe M, which connects with a suitable air-storage tank m. The end of the air-pipe within the dome is bent downwardly, as at m and on theoutside of the faucet is a stop-cock m by which the air can be shut off from any faucet without interfering with others connected with the same main-supply air-pipe m which leads to the tank m.

The air-regulating device is composed of a circular and flat flexible diaphragm G, having its edges supported and held between the edges of the collar (1 and the cover (1 The center of the diaphragm is perforated, and the hole is surrounded on the lower side with a washer g and on the upper side with an inverted cup 9 into which projects the vertical stem g of a yoke 9 the lower end of which has an enlarged extension with a vertical threaded opening therethrough. Into said enin a screw is inserted u on the upper end of which is secured a small disk of rubber or leather, adapted to close the opening in the pipe m when the yoke is moved upwardly by the corresponding flexion. of the diaphragm to which the stem of the yoke is secured. Normally the diaphragm is flexed in position.

downwardly by the spring the lower end of which bears against the peripheral flanges of the cup 9 When the air-pressure is in excess of the amount required to force the beer up through the pipes, the diaphragm will be flexed upwardly by the pressure thereon exceeding the resistance of the spring g and the yoke will be raised, so as to bring the disk on the end of the screw against the end of the pipe m thus shutting off the supply of air to the faucet. The vertical play of the yoke is controlled by the adjustability of the screw in the lower portion of the yoke, and the tension of the spring is modified by screwing upwardly or downwardly the cap d', as will be readily apparent.

Screwed into the forward end of the faucet and communicating with its beer-channel is a nozzle a supplied with a suitable cook a, through which the beer is drawn. The fancet is inserted in a suitable support or partition a on the front side of which is a sleeve a, surrounding the faucet and screwed thereon at al and a jam-nut a secures the faucet At the rear end of the faucet a double-channeled elbow F is secured by a coupling f and communicates with the double-channeled pipe 0, which passes through an ice-box 0 where it is coiled, and leads to the kegs in the cellar, which are supplied with my improved bung E and coupling device H. The bung is provided with an internally-threaded neck 6, into which is screwed the coupling device H, and is formed with an elbow 6 with which the air-tube e and the check-valve e are connected. The air-tube e is connected by a suitable coupling with an elbow 6 which is screwed into an opening in'the side of the bung and pipe-coupler H. The latter is cylindrical and formed with a central passage-way h for the beer and an annular chamber h surrounding said central passage. The coupler H is connected with the pipe ortubing O by a union h formed in two parts which fit over and around the adjacent edges of the coupler and pipe 0. The lower end of the pipe is formed with a flaring extension b, which rests upon the grooved edge of the interior wall it of the coupler H.

When the parts are assembled, the air-chamher in the pipe 0 communicates with the aircha mber h in the coupler H without reference to the position to which the latter is turned, as will be seen in Fig. 4E. The beertube J isarranged in the bung E and extends to the bottom of the beer-keg in the usual manner. Various modifications may be made in the details of construction and arrangement of this portion of the apparatus without affecting the principles embodied in the construction shown. As the pipe 0 is rigid and fixed, it is necessary to provide a certain amount of vertical adj ustability in the means for connecting the bung and pipe, as some kegs are higher than others, and any other means of accomplishing this than the threaded joints shown may be utilized.

As the pipe 0 conveys both beer and air, the latter will be cooled in the ice-box before being conducted to the beer, thus keeping a volume of cold air on the liquor at all times.

The position of the air-gage on the faucet enables the attendant to see at all times just how much air-pressure is on the beer, so that he can increase or diminish thesupply, as required, by manipulating the cock m By conducting the air and beer through a common pipe it is necessary to bore but one pipehole for each keg and faucet.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In an apparatus for dispensing beverages, a faucet having an air-channel and a liquidchannel therein, means for automatically regulating the admission of air to said air-channel from a suitable source of air-supply under pressure, an air-pressure gage communicating directly with said air-channel, a single pipe having formed therein a liquidchannel and an air-channel communicating respectively with like channels in the faucet, a bung having ways therein for air and liquid respectively and an adjustable device for coupling said bung and pipe, said device having an air-channel and a liquid-channel communicatin g respectively with like channels in the pipe, and bung, as set forth.
